    Sorry but the patch is just bogus. X-bit only code is usually
    a very bad sign for the code. This is not windows programing after all.

    Even if you wanted to do a 64bit only driver -- which
    you probably don't -- the standard way would be to exclude
    it in Kconfig.

    Please root-cause why symbol_request doesn't work on 32bit
    and fix it properly.
